disneyplus.com email security: SPF, DKIM & DMARC

Recommendations

1. 1Upgrade your DMARC policy from p=quarantine to p=reject for full blocking▾

   With p=quarantine, spoofed emails are sent to spam instead of being blocked outright. Some recipients still check spam folders, and sophisticated attacks can be flagged as legitimate by users. p=reject ensures fraudulent emails never reach any folder.

2. 2Add an SPF record: yourdomain TXT "v=spf1 include:yourprovider -all"▾

   SPF tells receiving servers which IP addresses are allowed to send email for your domain. Without it, any server in the world can send emails appearing to come from you. Adding SPF with -all (hardfail) means unauthorized senders will be rejected.

3. 3Enable DKIM in your email provider and add the public key to your DNS zone▾

   DKIM adds a cryptographic signature to your emails, proving they haven't been tampered with in transit and genuinely originated from your domain. Without it, attackers can forge emails that pass basic checks, and your legitimate emails are more likely to land in spam.

4. 4Add MTA-STS to enforce TLS encryption for incoming emails▾

   Without MTA-STS, an attacker performing a man-in-the-middle attack can downgrade the connection between mail servers to plaintext, intercepting emails in transit. MTA-STS tells sending servers to only deliver via TLS with a valid certificate, preventing downgrade attacks.
